Q2 LOGISTIC REGRESSION MODEL (12 pоints) Fоr the multiple regressiоn аnаlysis in this question, use the "trаinData". A. (7 points) Create a logistic regression model using “Churn” as the response variable and the following predicting variables: “DeviceRegistered”, “WatchlistSize”, “SupportTicketsPerMonth”. Call it model1. Display the summary of the model. i) What is the baseline for DeviceRegistered? ii) Give an interpretation of the coefficient of DeviceRegisteredTV with respect to log-odds and odds of being churned. State any assumptions while interpreting the coefficients. iii) Is the coefficient of WatchlistSize statistically significant at 0.01 significance level? Give reasoning. iv) Provide the equation for the estimated logit transformation of the probability of being churned given the predicting variables. B. (5 points) Create a logistic regression model using “Churn” as response variable and all the other variables as predictors. Call it model2. Display the summary. i) Perform a test for overall regression of the logistic regression model2, using αα =0.05 does the overall regression have explanatory power. Explain.
